Powerful Scripting
No XML. No DSL. Just familiar scripting with ES6 JS
import http from 'k6/http';
import {check, sleep} from 'k6';
export default function() {
const data = {username: 'username', password: 'password'};
let res = http.post('https://myapi.com/login/', data);
check(res, { 'success login': (r) => r.status === 200 });
sleep(0.3);
}Still stuck with JMeter?
No more GUI testing tools.
Upgrade to a better developer experience.
What our users are saying
Code-driven, JavaScript load tests that fit into our existing tool chain, clean APIs, command line so easy to automate and with a flag can run the same load test from the cloud in multiple locations. Haven’t had time to blog about it but k6 came out top of multiple tools tested
Toying around with @k6_io tonight. Pretty impressed with how easy it is to set up (yay @Docker!) and to start building test scripts. Some early results: pic.twitter.com/LGCESvFMlv
I have been working with K6.io it's nicer compared to other load testing frameworks I have used.
I've been tinkering with load testing recently and discovered @loadimpact. I'm absolutely loving it! I got up and running in minutes. Its UI is intuitive, and being based on JS makes it a breeze to start writing tests. That's not even mentioning the amazing open source k6! 😍
personally using @k6_io and its has helped us quite a lot already. Definitely worth adding to your testing pipeline.
Just discovered @k6_io very nice and simple tool for load testing
Old faithful JMeter, but we've also used @LoadImpact in the past which I'd highly recommend
Can't believe how easy and powerful load testing is with @LoadImpact!
@LoadImpact it's great stuff. My fav load testing I've found to date
